Abstract
A plastic material made from a polymer blend, is characterized in that said material contains at least one lignin-based natural polymer, in particular based on alkali lignin produced during the extraction of cellulose, and at least one other synthetic and/or natural polymer which increases the impact resistance, proteins excluded. The inventive plastic material has excellent characteristics. It is biodegradable due to the natural polymer content and has, to a considerable extent, an ecologically neutral CO balance. The polymer blend can be used advantageously in place of wood or wood materials.
